Lithium2400 Portable Power Station | Mobile Dual Battery System
- Out of stock
Mobile dual-battery system for overlanding, caravans, trailers and backup power — charge while driving, camp with confidence, and use it beyond the vehicle.
On Back Order until mid August 2026
The Lithium2400 is Flexopower's flagship Mobile Dual Battery System. It connects directly to your vehicle alternator — no DC-DC converter required — charges while you drive, and moves with you between vehicle, trailer, camp and home. A smarter, more flexible alternative to a fixed dual-battery installation.
With up to 30A alternator charging, plus AC and solar input options, the Lithium2400 is designed for people who want dependable onboard power with far more flexibility than a permanently installed system.
For end users, that means one system that works across vehicle, trailer, camp and home.
For installers, it means a cleaner, simpler and faster fitment path than many traditional custom electrical setups.
